Product information "Orchi-Bark Premium 0 (1-3mm)"

In nature, orchids grow as epiphytes on trees. The orchids cling to the tree bark. They can absorb the nutrients they need through precipitation and blown-on organic material. Bark-containing substrates are therefore particularly suitable for orchids, as these most closely resemble their natural environment. In conventional potting soil, the orchid roots would suffocate due to a lack of air.
The basis for an orchid substrate is always bark. Due to global forestry, pine bark of consistent quality is the easiest to obtain.
Cultivating orchids in pure bark is not easy. Almost none of the professional gardening companies cultivate the plants in pure bark these days. A water-storing permanent humus should always be added to the bark. Sphagum, white peat or coconut substrate can be used for this. The choice of permanent humus depends not only on availability and price, but also on the quality of the bark and the fertilizer used.
Soft bark likePinus sylvestris(Orchi-Bark) easily absorbs water, releases it easily, and is an optimal option for 1-2 years. Pine bark fromPinus sylvestris(Orchi-Bark Plus) is significantly harder, bast-free and the bark slowly absorbs moisture after 1-2 months in culture. InPinus sylvestris(Orchi-Bark Plus) the plants can be cultivated for up to 3 years without transplanting. The bark ofPinus mercus(Orchi-Bark Premium) is very hard, lasts up to 5 years, but it takes a very long time for the bark to absorb moisture.
All the barks we offer are heated in huge drums to 80-90°C for a short time, which kills insects and pests.
